I believe those amp requirements exceed what is used in a large MRI facility which the breakers where at 2200 amps if I remember correctly. (also at 480 V 3 phase)
When I was getting radiation treatments for cancer, I could hear a big honkin’ breaker thunking in when they were shooting at me, LOL.
Wow. That’s amazing.
I wonder if all that power (more than 2MW, almost 3000 HP) was needed continuously, or only needed when the magnets were being charged up.
Bulk electrical power is something like $100/MWh at best. That’s a lot of operating costs right there.
